Error: /dev/zram0: unrecognised disk label<br>

And syslog shows a slew of errors:<br>
<br>
Lubuntu kernel: Buffer I/O error on device zram0, logical block 128247<br>
<br>
Syslog also indicates that half of memory was given to zram to form its block device.<br>
<br>
Does this mean that half of memory is dedicated to something that isn't working? And perhaps that machines will hang when swap is needed?<br>
<br>
I arrive at this line of questioning because I was testing an LTSP client using a Lubuntu LTSP server configured with 1 GB, and when I drop the client memory configuration to 256 MB, the *server* has hung on several occasions when I was starting or stopping Firefox on the client (though in one case this coincided with the startup of a SpiderOak backup operation). I didn't think of the Magic SysRq keys at the time, and nothing else was responding, so I did hard shutdowns.<br>
<br>
I saw a post from Phill Whiteside recently concerning a rush of activity re a zram bug, but it seemed to be directed at Saucy.<br>
<br>
Are there solutions/workarounds?<span class="HOEnZb"><font color="#888888"><br>
